I don't think that all the decode and formatting of these registers should be in the kernel. Every time I've had to mess with register decode stuff for investigation, I've needed to extend the decode. Instead, we should expose the raw register values and make intel_reg_dumper in intel-gpu-tools that does the decode of actual meaning. -- Eric Anholt [email protected] [email protected]
